Jaguar’s new electric concept supercar -- the C-X75
(PhysOrg.com) -- The new Jaguar C-X75 supercar concept model unveiled last week is primarily a plug-in electric car but with the added power and performance of micro gas turbines (jet engines) that would make it the fastest ...
Thrusters powered by ionic wind may be efficient alternative to conventional atmospheric propulsion technologies
When a current passes between two electrodes—one thinner than the other—it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel.
